Struct AnimatedScrollState

Source

pub struct AnimatedScrollState {
    pub current_offset: LogicalPosition,
    pub previous_offset: LogicalPosition,
    pub animation: Option<ScrollAnimation>,
    pub last_activity: Instant,
    pub container_rect: LogicalRect,
    pub content_rect: LogicalRect,
}

Expand description

The complete scroll state for a single node (with animation support)

Fields§

§current_offset: LogicalPosition

Current scroll offset (live, may be animating)

§previous_offset: LogicalPosition

Previous frame’s scroll offset (for delta calculation)

§animation: Option<ScrollAnimation>

Ongoing smooth scroll animation, if any

§last_activity: Instant

Last time scroll activity occurred (for fading scrollbars)

§container_rect: LogicalRect

Bounds of the scrollable container

§content_rect: LogicalRect

Bounds of the total content (for calculating scroll limits)
